Application iled June 16, 1927. Serial No. 199,256,

This linvention relates to a mechanism for using toilet paper and has for its object the provision of an apparatus for this purpose which performs this function in a manner which is sanitary and avoids possible contagion.

In the accompanying drawings:

Figure 1 is a vertical longitudinal section of a water closet equipped with my invention. Figure 2 is a perspective of the main parts of theA apparatus containing my invention. Figure 3 is a bottom plan view of the apparatus, on an enlarged scale. Figures 4, 5, and 6 are fragmentary views, similar to Fig. 3, on a reduced scale, showing different positions of the working parts. Figure 7'/ is a vertical section, on an enlarged scale,l

taken on line 7--7, Fig. 5, and showing one position of the mechanism ufor severlng .the toilet paper. Figure 8 is a similar view showing the parts in another position. Fig.

ures '9, 10 and 11 are fragmentary vertical sections taken on the correspondingly numbered lines in Figs.- 5, 4 and 3 respectively. Figure 12 is a fragmentary vertical longitudinal section taken centrally through the Y ings.

The numeral 20 represents the body of a commode, 21 the seat-having an opening 22, 23 the pot arranged below said opening, and separated therefrom byv a gap 24, and

' 25 a pocket arrangedin the commode in rear of said gap. The apparatus for using toilet paper is mounted, on a carrlage 26 which is movable back and forth froma position in said pocket to a position in said gap in between lthe seat opemng and s a1d pot and may be guided Aby longltudinal shoes or runners 27 on the opposite edges of y -the carriage sliding on rails 28 secured to the `body of the commode. Forward and backward movement of the carriage may be.

lmounted Ia wiping ,wheel or roller which turns about a horizontal transverse axis and has a V-shaped'body 32 the 'summit of whose periphery has a circumferential groove 34,

power which is preferably obtained from an electric motor 39 mounted on the rear part of the carriage. Motion at a reduced speed 1s transmitted'from the shaft 40 to the wiper shaft 38 by means consisting preferably of a p horizontal counter shaft 41 arrangedv transversely below the wiping wheel and journaled ina suitable bearing on the carriage, a belt 42. passing around small and large pulleys '43, 44m'0unted respectively on the motor shaft and the counter shaft, and a gear pinion 45 arranged on the counter shaft and meshingwith a gear wheel 46 on the wiper shaft. The motor is arranged in an electric circuit which includes an electric ygenerator 47 or other suitable electric source and a switch 48 for opening and closing this circuit so, asfto stop and start themotor.

In frnt'f the lower part of the wiping wheel is arranged a horizontal delivery shaft 49 which is journaled in suitable bearings on the carriagev and is provided adjacent to the opposite sides of the lower front part of the wiping wheel with inner and outer delivery wheels 50, 51 each of which has its periphery preferably constructed of polygonal form, as shown in Figs. 2 and 12.

The toiletlpaper in the form of a web, sheet or strip 53 is supplied from a roll 54 which is mounted on an axle 55 supported on standards 56 rising from the carriage between the motor and the wiping wheel. This strip passes from the roll forwardly under a guide 57 arranged below the wiping wheel, thence upwardly along vthe front sidev of the counter shaft 4,51, thence rearwardly and upwardly around the rear side of the wipin wheel, thence forwardly over the top of this wheel and thence forwardly and downwardly over the front side of the delivery wheels 50, 51. As the strip of paper Ivgasses around the wiping wheel the same is rawn tightly against the body and the hubs thereof so that the central part of the strip assumes a V-form in cross section the summit ofv which is elevated while 'fthe edge portions are depressed and clamped, against the hubs of the body so as to compel the strip of paper loo and the Wi )ing wheel to turn forwardly together during thegoperation of withdrawing paper from the supply roll and moving the V-shaped part thereof past the surface to be cleaned.

As the paper strip passes upwardly in front of the counter shaft and around the rear and top parts of the wiping wheel the longitudinal central par't of the strip is enraged on its inner side by a central delivery belt 58 which passes around the groove in the summit of the body and also around a pulley 59 formed by the central part Qf the deliver shaft 49. As the paper strip passes upwar ly in front ofthe counter shaft 41 each of its edges passes upwardly between the inner side of the feeding-on stretch 60 of a gripping belt and the outer side of the feeding-on stretch 61 of a side guide belt, said feeding-on stretches G0, 61 converging upwardly so that the lower parts of the same are separated, as shown in Fig. 12, and permit the respective edges of the paper strip to pass upwardly between them, while the upper parts of said feeding-on stretches 60, 61 run side by side around the grooves in the respective hubs of the body, and thereby cause the upper gripping turn 62 of the. gripping belt to press the paper strip against said hub and the upper turn 63 of the gripping belt to pass around said hub underneath the paper strip between its gripped edge portion and the V-shaped central part, as shown in Fig. 13. By this means a firm hold is obtained on the pa er at its edges only which insures positive orward turning of the same with the wiping wheel while the central V-shaped part of the paper strip is elevated above the gripped edges of the same and unobstructed so that no parts of the gripping belts are liable to become soiled while the paper is being moved in engagement with the surfaces to be cleaned.y thereby preventing the apparatus from becoming foul or unsanitary.

The lower end of the feeding-ou stretch of the gripping belt passes around a pulley 64 formed by the adjacent part of the counter shaft 41 and connects with one end of a rearwardly defiected turn 65 of the gripping belt whichl passes around a rear guide pulley 66, and the vfront end of the gripping turn 62 of this belt connects with the upper end of a feeding-off stretch 67 of this belt, the lowerend of this feeding-oil" stretch passing around the front and underside of a frontguide dpulley 68 vand conneci'f` ing with theotlfer en of the turn 65 of this belt which passes around the rear guide pulley 66. Each of the `side guide belts has a front feeding-oif stretch 69 extending from the upper turn 63 downwardly and forwardly around the front side of a lower 'guide roller or pulley 70 formed on the delivery shaft 49 and then passing rearwardly lunderneath this mlley and connecting with the lower end ot the feeding-on stretch of this belt.

By means of the u per front or feedingoff stretches of the ielts, the paper strip, after performing a wiping operation onthe upper art of the wiping wheel, is released from t le same and delivered forwardly and downwardly therefrom to the delivery rollers orpwheels 50, 51 which latter preferably direct the papel' to the pot 23 which is arranged below the toilet seat opening.

In order to insure disengagement ofthe edge of the strip or web of the paper from the gripping and guiding belts after thc wiping operation has been performed,strip ping means are provided consisting pref.

era-bly of a plurality of fingers 71 arranged adjacent to the delivery parts of the gripping and guiding belts and delivery wheels and serving to deflect the used part of the paper away from the feeding-off stretches of the belts and thus avoiding clogging of the apparatus with soiled paper. I

These stripping fingers and the front and l'car guide ro lers 68 and pulleys 66 may be mounted in any suitable manner on the adjacent parts of the carriage, as shown in Figs. 1, 2, 3 and 12.

,While a person is occupying the seat and using the commode the wiping mechanism is retracted from the gap between the seat and thel pot so as to permit unobstructed passage from the seat to the pot and during this time the motor is shut ofi' and rendered inoperative. lVhen, however, the person has finished and is ready for wiping then the electric switch 48 is closed so that the motor will operate the paper actuating meenanism. lVhile the motor is running the carriage is moved from its rearward position in the pocket 25 of the commode',- as shownby vfull lines in Fig. 1, to its forward position in the gap between the seat and the pot, as shown by dotted lines in the same ligure, whereby the upper V-shaped part of the wiping wheel not only sweeps the crotch of the person but 'also rotates in engagement therewith, thereby passing a considerable length of the paper web or Strip over the parte. to be cleaned and efectiyely removing vthe wiping apparatus is still between the seat and the pot the paper web or strip is severed above the soiled part so that the lat-- ter drops into the pot. This severing operatic-1,1 is preferably effected automatlcal y any mattei' therefrom. After this 'wiping by means which lows The numeral 72 represents the stationary blade of a pair of cutting shears and 7 3 the movable blade of the same, these blades being pivotally connected by a vertical pin 74 and the stationary blade being secured transversely to the front part of the carriage. While the carriage is being moved forwardly the movable blade is swung rearwardly so as to open the shears and the same remain open while the carriage is between the seat and the pot, thereby permitting the web or sheet of paper to be moved from the wiping wheel downwardly between the blades of the shears and into the pot.' As the carriage is moved rearwardly the movable blade is swung across the relatively fixed blade of the shears and thereby severs the web of paper and permits the lower advancing end to drop inmay beconstructed as fol-- to the ot. The movable blade is yieldingly held eit er in its open position or in its closed position by means of a locking lever 75 pivoted on the carriage and having its forwardly proj ectingfree end connected by a link 76 with a tail 77 arranged on the inner` end of the movable blade and a tension spring 78 connected at one end with the carriage and connected at its other end by a link 79 with. the locking lever. When the shears lare closed and the movableblade is swung forwardly the connection between the spring 7 8 and the locking lever is on the outer side of the pivot of this lever whereby the pull of this spring holds the movable blade shut, as shown by full lines in Fig. 3, at which time the closing movement of the movable blade is limited by a stop 80 on the carriage engaged by the tail of the movable blade. Upon swinging the movable blade open the tension on the spring 78 is increased until the locking lever 75 has been turned in the opposite direction suiicient to bring. the connection `between the spring 78 and the locking lever on the inner side of the pivot of this lever, and when this occurs the tension of this spring quickly completes the opening movement of the movable blade, the movement of the parts in this direction being limited bya stop 81 on the locking lever engaging the adjacent part of the carriage, as shown by dotted .lines in Fig. 3, and by full lines in Fig. 5. The initial part of the turning movement of the movable bladle for closing the same is effected during the initial part of the backward movement ot the carriage by engagement vof a cam 8-2 on l the tail of the movable blade with a Istationary trip pin 83 on the adjacent part of the commode, such as one of the rails 28, which cam and pin turn the movableblade far enough to swing the locking lever 75 past its dead center and then, the spring 78 completes this closing movement of the movable blade. The initial part of the opening movement of the movable blade is effected by a shifting lever 84 pivoted on the carriage and having one of its arms connected by' a link trip arm 87 by' engagement/c with the shifting lever 84 turns the latter suliiciently to swing the locking leverpast its dead center in the cutter opening direction and thereafter the completion of the closing movement f the movable cutter blade is effected by the tension spring 78.

During the backward movement of the carriage the trip arm- 87 must be moved out ofthe path ofthe shifting lever 84' so that the latter can swing forwardly freely during the quick closing movement of the movable cutter blade, this being accomplished by a delecting pin90 mounted on the carriage and adapted to engage the front side of the trip arm 87, as shown in Figs. 5 and 7, 'and push the same rearwardly out of the path of the shifting lever so that the latter is free to swing from its rearward position shown in Fig. 5 to its forward position shown in Fig. 6 for closing the shears without interference from the trip arm 87. During the last part of the backward movement of the carriage the shifting lever 84 again deflects the trip arm 87 in order to get behind it and engage therewith, as shown in Fig. 4, during the initial part of the subsequent forward movement of the carriage for again opening the movable cutter blade.

. In order to permit the deiecting pin 90 to clear the trip arm 87 during the forward movement of the carriage this pin is provided with an inclined front side 91 which is adapted ,to engage an inclined rear side 92 on the trip arm 87, as shown in Fig.` 8, and thereby depress this pin so as to clear the trip arm. Such depression ofthe deflecting pin is rendered possible byv mounting the same on a guide rod 93 which slides vertically in the bottom of a pocket 94 on the carriage, and a spring 95 which yieldingly holds the deflecting pin in its operative position and `bears with its ends against the bottom of this pocket and the underside of said deflecting pin, as shown in Figs. 7 and 8. During the forward or closing movement of the movable cutter blade the adjacent art of the strip of paper to be cut is pushed orwardly into the crotch of the shears by a push finger 96 arranged on 1the free end of the shifting lever.

It will be'apparent that the operation of cutting the strip o f paper is elitected automatically during the return movement of the wiping mechanism lfrom its forward wiping position to its rearward inactive position and that at no time are the hands of a peison required for using the toilet paper after the toilet has been' used.
